IPC: H04N5/265
Filed: 1992-06-03
Abstract: PURPOSE:To prevent the flicker of a video at the time of the switching of a horizontal synchronizing signal by selecting an appropriate horizontal synchro nizing signal according to a synchronization switching control signal, and adding it to a mixed video signal. CONSTITUTION:A CPU 1 judges the rate of a playing video signal to a graphic video signal in one horizontal scanning period, generates the synchronization switching control signal according to the judged result, and supplies it to a fade control circuit 14. The circuit 14 repeats a high level output to a mixing circuit 9 when the level of the synchronization switching control signal is high, and the circuit 9 outputs the horizontal synchronizing signal of the playing video signal as it is. On the other hand, the circuit 14 repeats a low level output to the circuit 9 when the level of the synchronization switching control signal is low, and the circuit 9 outputs the horizontal synchronizing signal of the graphic video signal as it is. Thus, the appropriate horizontal synchronizing signal is selected by each line, so that the flicker of the video generated at the time of the switching of the horizontal synchronizing signal can be prevented.

Abstract: PURPOSE:To dissolve calcium sulfate on a diffusing pipe to prevent clogging by intermittently diffusing ozonized gas when the ozonized gas is diffused into sea water of an ozone contact column to ozonize the sea water, and filling the diffusing pipe with sea water when the diffusing is stopped. CONSTITUTION:Sea water 1 is pumped up from, for example, a sea-water fish raising tank 2 by a pump 3 and fed into an ozone contact column 4. Ozonized air is formed by feeding air into a dehumidifier 6 by an air compressor 5 before introducing it into an ozonizer 7. Further, the ozonized air is fed into the ozone contact column 4 and injected as bubbles 9 into the sea water 1 from a diffusing pipe 8.

IPC: B60K17/346
Filed: 1986-06-20
Abstract: PURPOSE:To improve turning round performance without impairing stability in straight running by providing a sensor detecting the steering force of a handle whereby distributing much more torque to rear wheel driving depending on the steering force of the handle. CONSTITUTION:The steering force of a handle is detected by a handle steering force sensor 22 whereby hydraulic pressure which increases torque distribution to rear wheels depending on the quantity of steering force, is applied to a hydraulic clutch 11 by a torque distribution control device 20. Then, torque generated by the clutch 11 is reduced from front wheel driving torque, and furthermore the same is added to rear wheel driving torque in such a way as to be distributed much more to rear wheel driving while bypassing a center differential gear 7. Owing to this constitution, stability in straight running can be secured and a tendency of understeering on a road with a high value of muis negated, thereby ensuring a satisfactory turning round performance.
